Hydraulic actuators are devices that convert hydraulic energy into mechanical motion. They use pressurized fluid to create movement, allowing them to perform tasks such as lifting, pushing, or rotating. Commonly found in machinery and vehicles, these actuators are essential for applications that require significant force and precision. The basic components of a hydraulic actuator include a cylinder, piston, and hydraulic fluid. When the fluid is pumped into the cylinder, it pushes the piston, resulting in movement. This technology is widely used in industries like construction, automotive, and aerospace, where reliable and powerful motion is necessary for operations involving heavy loads or complex mechanisms.
